Description

Technical Field

[0001] The present invention relates to the technical field of gas generators, and more particularly, to a gas generator and an installation method thereof. Background Art

[0002] As a key power supply guarantee device, the heat dissipation performance of a gas generator directly determines its operating reliability, energy efficiency, and service life. Under high-temperature and high-load conditions, the internal temperature of the generator can quickly rise above 120°C. If the heat dissipation is poor, a series of serious problems will occur: 1. High temperature causes the insulation layer of the winding to age rapidly (the insulation life is halved for every 10°C increase in temperature), greatly increasing the risk of short circuit. The performance of electronic components (such as IGBT modules) deteriorates rapidly when the temperature exceeds 85°C, and the misoperation rate of the control system increases by 300%. Mechanical components such as piston rings and bearings experience exponential growth in wear rate due to thermal expansion mismatch.

[0003] 2. Under high-temperature conditions, the ECU is forced to derate, and the output power attenuation can reach 15 - 20%. The energy consumption ratio of the cooling fan climbs to 8 - 12% of the total power consumption, forming a vicious cycle, which is an inherent defect of the traditional air-cooling system. For every 10°C increase in the intake air temperature, the power generation efficiency decreases by 2 - 3%, and the fuel consumption increases by more than 5%.

[0004] 3. In desert areas, the high temperature of 55°C during the day causes the heat dissipation system to completely fail. The failure rate of backup power supplies in data centers due to insufficient heat dissipation reaches 34%. Offshore units have a combined failure mode of salt spray corrosion and blockage of heat dissipation holes.

[0005] Traditional heat dissipation methods mainly rely on forced ventilation and air exchange, that is, external cold air is introduced into the generator compartment through a fan, and then the hot air is discharged to achieve heat exchange. However, this heat dissipation method has the following significant problems: 1. The forced ventilation system usually relies on a high-speed rotating fan, resulting in relatively large airflow noise and mechanical vibration noise. In places with high noise requirements such as residential areas, hospitals, and data centers, this noise may exceed environmental protection standards and affect the surrounding environment.

[0006] 2. In summer or high-temperature environments, the external air temperature may reach above 35°C, resulting in a relatively high initial temperature of the cooling air entering the generator compartment, and the heat dissipation capacity is greatly reduced. At this time, even if the ventilation volume is increased, it is difficult to effectively reduce the internal temperature of the equipment, which may cause overheat protection shutdown and affect the power supply stability.

[0007] 3. In order to maintain sufficient heat dissipation capacity, the generator often needs to continuously operate a high-power fan, which will consume additional electrical energy and reduce the overall energy utilization rate.

[0008] 4. The open ventilation system is prone to inhaling external dust, moisture, or corrosive gases (such as salt spray in coastal areas), accelerating dust accumulation inside the equipment and circuit corrosion, and affecting the lifespan of the generator.

[0009] Therefore, there is an urgent need for an efficient heat dissipation solution that can effectively reduce the operating temperature of the gas generator and reduce noise pollution, especially suitable for high-temperature environments or scenarios with strict noise requirements. Summary of the Invention

[0010] The purpose of the present invention is to provide a gas generator and an installation method, which can dissipate heat from the gas generator through the constant temperature characteristics of the formation, thereby reducing the noise caused by a large amount of air exchange inside and outside the box.

[0011] The embodiments of the present invention are achieved through the following technical solutions: A gas generator includes a box body, a generator set, and a cooling system; the generator set is installed inside the box body; the box body is provided with a group of ventilation pipes communicating inside and outside; the ventilation pipes are connected to the air inlet or exhaust port of the generator set; the cooling system includes a delivery pump, a heat exchanger, and heat exchange pipes; the delivery pump, heat exchanger, and heat exchange pipes are connected end to end in sequence to form a circulation path, so that the delivery pump drives the working medium to circulate between the heat exchanger and the heat exchange pipes; the heat exchanger is provided with a fan and the fan is arranged inside the box body; the heat exchange pipes are inserted into the formation.

[0012] Further, the box body is placed on the ground; an equipment pit is arranged below the box body below the ground; the delivery pump is arranged inside the equipment pit; there are several heat exchange pipes and all are connected to the delivery pump; several heat exchange pipes are evenly inserted into the bottom of the equipment pit.

[0013] Further, the heat exchange pipe includes an outer pipe and an inner pipe inserted inside the outer pipe; one end of the outer pipe is open and the other end is closed; a spiral fin is arranged on the outer wall of the outer pipe.

[0014] Further, a spiral fin is arranged on the outer wall of the inner pipe; the outer diameter of the fin is the same as the inner diameter of the outer pipe.

[0015] Further, the heat exchange pipe further includes a connection cover and a connection nut; the connection cover is threadedly connected to the open end of the outer pipe and closes the opening of the outer pipe; the connection cover is provided with a through hole to enable the inner pipe to extend out through the through hole; a limiting step is arranged on the inner pipe inside the connection cover; the connection nut is connected to the inner pipe and is located outside the connecting rod, so that the connection cover is clamped between the connection nut and the limiting step; a connection nozzle communicating inside and outside the container is further arranged on the side of the connection cover.

[0016] Further, one end of the outer tube is sealed by a sealing plug; the sealing plug is threadedly connected to the inside of the outer tube; the sealing plug is provided with a conical guiding cone; the tip of the guiding cone faces the center of the inner tube.

[0017] Further, a sealing ring is also provided between the limiting step and the connecting cover.

[0018] Further, the gas generator includes a power generation skid and a control skid; the generator set and the cooling system are both arranged inside the power generation skid; a control cabinet is arranged inside the control skid; a connecting port is cooperatively arranged at the top of the power generation skid and the bottom of the control skid, so that the control skid can be placed and connected to the top of the power generation skid; the ventilation pipe is connected to the control skid.

[0019] A gas generator installation method includes the following steps; S1: Excavate an equipment pit; and drill a number of installation holes into the formation from the bottom of the equipment pit. S2: Insert a number of heat exchange tubes into the installation holes and connect the number of heat exchange tubes to a delivery pump. S3: Install the skid-mounted gas generator on the ground and connect the heat exchanger to the skid-mounted gas generator.

[0020] Further, step S2 further includes a method for inserting the heat exchange tube into the installation hole: S21: Fill the installation hole with bentonite; rotate the outer tube and insert it into the installation hole, so that the spiral fins are screwed into the bentonite and enter the installation hole. S22: Insert the inner tube into the inside of the outer tube. S23: Tighten the connecting cover onto the outer tube and make the inner tube extend out through the through hole of the connecting cover; and tighten the connecting nut onto the inner tube. S24: Connect the inner tube to the outlet end of the delivery pump; connect the connecting nozzle to the inlet end of the heat exchanger.

[0021] The technical solution of the embodiment of the present invention has at least the following advantages and beneficial effects: When the gas generator of the present invention is in use, the intake and exhaust of the generator set each pass through a ventilation pipe, and thus are directly communicated with the outside atmosphere without exchanging air with the air inside the box body. At the same time, the delivery pump circulates the refrigerant, so that the refrigerant circulates between the heat exchanger and the heat exchange tubes; when the refrigerant passes through the heat exchange tubes, it exchanges heat with the soil inside the formation and cools down. Subsequently, the refrigerant flows to the heat exchanger. The fan drives the air flow inside the box body to flow through the heat exchanger to the generator set, so that the air flow is cooled at the heat exchanger and then flows to the generator set, thereby dissipating heat from the generator set. At the same time, the air inside the entire box body is also cooled.

[0022] Adopting such a cooling system enables the air inside the box body not to exchange heat with the outside air, so there is no need to ventilate the box body. This greatly reduces the noise generated during the operation of the gas generator. Since the cooling system does not communicate with the outside air, the heat dissipation effect will not be affected by the high external temperature in summer. At the same time, the inside of the box body is an independent environment, which is not easy to inhale external dust, moisture or corrosive gases, reducing dust accumulation inside the equipment and circuit corrosion, and ensuring the service life of the generator.

[0023] The cooling system is arranged inside the equipment pit, so that the noise it emits is largely restricted underground, thereby reducing the noise. At the same time, the equipment pit itself has a depth of one to two meters, enabling the heat exchange pipes to be inserted into the ground as much as possible, and thus inserted into the depth with the most stable low temperature. This better ensures the heat dissipation effect.

[0024] Spiral fins are arranged on the outer wall of the outer pipe, enabling the outer pipe to rotate and enter the ground. During the process of screwing into the ground, the spiral fins are inserted into the soil, so that the contact area between the outer pipe and the soil is larger, which is more conducive to heat exchange. In practice, the installation hole is first filled with bentonite with good heat conduction, and then the outer pipe is screwed in. This tightly fills the gap outside the outer pipe. At the same time, after the outer pipe is inserted, the outer pipe can be screwed in the reverse direction to take it out, and thus recycled. Spiral fins are arranged on the outer wall of the inner pipe, making the path of the refrigerant flowing through the heat exchange pipe longer, and better exchanging heat with the soil.

[0025] The heat exchange pipe is set as several components including an inner pipe, an outer pipe, a connecting cover and a sealing plug, enabling each component to be processed separately. This makes the processing simple, and after combination, it can become a complex structure to achieve complex functions. The sealing plug is set so that the main body of the outer pipe is a straight pipe, which is convenient for cleaning the inner wall after disassembly. The guiding cone set on the sealing plug can disperse the liquid flowing out of the inner pipe to the surrounding areas, and then enter the inside of the outer pipe from the surrounding areas. This makes the refrigerant distribution inside the outer pipe uniform, and thus better exchanges heat with the soil. The gas generator is set in the form of a combined power generation skid and control skid, which can reduce the volume of the two skid-mounted devices and is convenient for transportation. In addition, the control skid can be stacked on top of the power generation skid, reducing the floor area. At the same time, the power generation skid can be installed inside the equipment pit, so that the main noise source is buried underground, and thus better reduces the noise. The power generation skid itself has a formed outer shell. For some temporary use places, there is no need to deal with the inner wall of the equipment pit too much, and the power generation skid can be directly put into the equipment pit.

Detailed implementation manners

[0034] As Figures 1 - 7 shown, the present invention provides a gas generator, which includes a box body 1, a generator set 2 and a cooling system. The box body 1 and the generator set 2 are both common components and are the same as common gas generators. The generator set 2 is installed inside the box body 1. The box body 1 is provided with a group of ventilation pipes 3 that communicate inside and outside. The ventilation pipe 3 is connected to the intake port or the exhaust port of the generator set 2. So that the intake and exhaust of the generator set 2 both pass directly through the ventilation pipe 3 to the outside of the box body 1, avoiding affecting the air environment inside the box body 1. The cooling system includes a transfer pump 4, a heat exchanger 5 and a heat exchange tube 6. The transfer pump 4, the heat exchanger 5 and the heat exchange tube 6 are connected end to end in sequence to form a circulation path. As Figure 2 shown, the transfer pump 4 drives the working medium to circulate between the heat exchanger 5 and the heat exchange tube 6. As Figure 1 shown, the heat exchanger 5 is cooperatively provided with a fan 7 and the fan 7 is arranged inside the box body 1. The heat exchange tube 6 is inserted into the ground, and then heat exchange is carried out with the soil inside the ground. The temperature of the ground is constant and close to the local annual average temperature, about 15 - 18 °C at 15 meters underground. This enables the refrigerant to be cooled to about 20 degrees when passing through the heat exchange tube 6. For the convenience of operation, the heat exchange tube 6 can be inserted 10 - 15 meters underground.

[0035] When the gas generator of the present invention is in use, the intake and exhaust of the generator set 2 each pass through a ventilation pipe 3, and thus are directly communicated with the outside atmosphere without exchanging air with the air inside the box 1. At the same time, the delivery pump 4 circulates the refrigerant, so that the refrigerant circulates between the heat exchanger 5 and the heat exchange pipe 6. When the refrigerant passes through the heat exchange pipe 6, it exchanges heat with the soil inside the formation and cools down. Subsequently, the refrigerant flows to the heat exchanger 5. The fan 7 drives the air flow inside the box 1 to flow through the heat exchanger 5 to the generator set 2, so that the air flow is cooled at the heat exchanger 5 and then flows to the generator set 2 to dissipate heat from the generator set 2. At the same time, the air inside the entire box 1 is also cooled.

[0036] Adopting such a cooling system can make the air inside the box 1 not need to exchange heat with the outside air, and thus there is no need to ventilate the box 1. The noise during the operation of the gas generator is greatly reduced. The cooling system does not communicate with the outside air and will not affect the heat dissipation effect due to the high external temperature in summer. At the same time, the inside of the box 1 is an independent environment, not easily inhaling external dust, moisture or corrosive gases, reducing dust accumulation and circuit corrosion inside the equipment, and ensuring the service life of the generator.

[0037] In this embodiment, the box 1 is placed on the ground. An equipment pit 8 is provided below the box 1 below the ground. The inner wall of the equipment pit 8 only needs to be slightly processed. The delivery pump 4 is arranged inside the equipment pit 8. A plurality of heat exchange pipes 6 are provided and are all connected to the delivery pump 4. The plurality of heat exchange pipes 6 can be connected in series or in parallel. The plurality of heat exchange pipes 6 are uniformly inserted into the bottom of the equipment pit 8 and inserted deep into the formation.

[0038] The cooling system is arranged inside the equipment pit 8, so that the noise generated by it is largely limited underground, thereby reducing the noise. At the same time, the equipment pit 8 itself has a depth of one to two meters, so that the heat exchange pipes 6 can be inserted into the ground as much as possible, and thus inserted into the depth with the most stable low temperature, avoiding the depth with large temperature fluctuations on the ground surface. Better ensure the heat dissipation effect.

[0039] In this embodiment, the heat exchange pipe 6 includes an outer pipe 9 and an inner pipe 10 inserted inside the outer pipe 9. One end of the outer pipe 9 is open and the other end is closed. The refrigerant enters the outer pipe 9 through the inner pipe 10 and flows out through the outer pipe 9. A spiral fin 11 is arranged on the outer wall of the outer pipe 9.

[0040] The outer wall of the outer tube 9 is provided with spiral fins 11, enabling the outer tube 9 to be rotated into the ground. During the process of screwing into the ground, the spiral fins 11 are inserted into the soil, thereby increasing the contact area between the outer tube 9 and the soil, which is more conducive to heat exchange. In practice, the installation hole 24 is first filled with bentonite 23 with good heat conduction, and then the outer tube 9 is screwed in. This makes the bentonite 23 tightly fill the gap outside the outer tube 9. If bentonite 23 is backfilled after the outer tube 9 is inserted into the installation hole 24, it is very difficult to fill the gap between the outer tube 9 and the inner wall of the installation hole 24 with bentonite 23, thus affecting the heat exchange effect. At the same time, after the outer tube 9 is inserted, the outer tube 9 can also be reversely screwed to take it out, and then recycled.

[0041] In this embodiment, the outer wall of the inner tube 10 is provided with spiral fins 12. The outer diameter of the fins 12 is the same as the inner diameter of the outer tube 9, so that the inner tube 10 can just be inserted into the inner part of the outer tube 9. The spiral fins 12 provided on the outer wall of the inner tube 10 divide the inside of the outer tube 9 into spiral channels, greatly increasing the length of the channels. This makes the path of the refrigerant flowing through the heat exchange tube 6 longer, and better exchanges heat with the soil.

[0042] In this embodiment, the heat exchange tube 6 further includes a connection cover 13 and a connection nut 14. As Figure 5 shown, the connection cover 13 is threadedly connected to the open end of the outer tube 9 and closes the opening of the outer tube 9. The connection cover 13 is provided with a through hole to enable the inner tube 10 to extend out through the through hole. The inner tube 10 is provided with a limiting step 15 inside the connection cover 13. The connection nut 14 is connected to the inner tube 10 and is located outside the connecting rod, so that the connection cover 13 is clamped between the connection nut 14 and the limiting step 15. Thus, the gap between the limiting step 15 and the connection cover 13 is sealed, preventing the refrigerant from leaking through the through hole of the connection cover 13. A connection nozzle 16 communicating inside and outside the device is also provided on the side of the connection cover 13.

[0043] The inner tube 10 is used to connect to the outlet end of the delivery pump 4, and the connection nozzle 16 is used to connect to the inlet end of the heat exchanger 5. Thus, the delivery pump 4 transports the refrigerant to the inner tube 10. The refrigerant in the inner tube 10 flows into the outer tube 9, then to the heat exchanger 5, and finally back to the delivery pump 4, thereby achieving the purpose of circulating transportation.

[0044] In this embodiment, one end of the outer tube 9 is sealed by a sealing plug 17. As Figure 6 shown, the sealing plug 17 is threadedly connected inside the outer tube 9. The sealing plug 17 is provided with a conical guiding cone 18, and the tip of the guiding cone 18 faces the center of the inner tube 10.

[0045] The sealing plug 17 is arranged such that the main body of the outer tube 9 is a straight tube. After the outer tube 9 is disassembled, the inner wall can be cleaned by inserting devices such as a brush, which is convenient for cleaning the inner wall after disassembly. The liquid flowing out of the inner tube 10 reaches the guiding cone 18 and spreads out in all directions under the guiding action of the guiding cone 18. Then the refrigerant enters the inside of the outer tube 9 from all around, making the distribution of the refrigerant inside the outer tube 9 uniform, and thus better for heat exchange with the soil.

[0046] The heat exchange tube 6 is set to several components including the inner tube 10, the outer tube 9, the connecting cover 13 and the sealing plug 17, which makes it convenient to process each component separately. This makes the processing simple, and after combination, it can become a complex structure to achieve complex functions.

[0047] In this embodiment, a sealing ring 19 is further arranged between the limiting step 15 and the connecting cover 13. Thus, the gap between the limiting step 15 and the connecting cover 13 is better sealed, avoiding the leakage of the refrigerant through the through hole of the connecting cover 13.

[0048] In this embodiment, the gas generator includes a power generation skid 20 and a control skid 21. The generator set 2 and the cooling system are both arranged inside the power generation skid 20. A control cabinet 22 is arranged inside the control skid 21. A connection port is arranged in a matching manner at the top of the power generation skid 20 and the bottom of the control skid 21, so that the control skid 21 can be placed and connected on the top of the power generation skid 20. The connection port can adopt the structure of container stacking connection. This structure is prior art and will not be elaborated in this embodiment. The ventilation pipe 3 is connected to the control skid 21. During installation, the power generation skid 20 is placed in the equipment pit 8, and the control skid 21 is placed and connected on the top of the power generation skid 20.

[0049] Setting the gas generator in the form of a combination of the power generation skid 20 and the control skid 21 can reduce the volume of the two skid-mounted devices, facilitating transportation. In addition, the control skid 21 can be stacked above the power generation skid 20, reducing the floor area. At the same time, the power generation skid 20 can be installed inside the equipment pit 8, so that the main noise source is buried underground, and thus the noise is better reduced. The power generation skid 20 itself has a formed outer shell. For some temporary use places, it is not necessary to process the inner wall of the equipment pit 8 too much, and the power generation skid 20 can be directly put into the equipment pit 8.

[0050] This embodiment also provides a method for installing a gas generator, including the following steps.

[0051] S1: Excavate the equipment pit 8. And drill a number of installation holes 24 into the formation from the bottom of the equipment pit 8. The distribution of the installation holes 24 can be set according to needs.

[0052] S2: Insert a number of heat exchange tubes 6 into the installation holes 24 and connect the number of heat exchange tubes 6 to the delivery pump 4.

[0053] S3: Install the skid-mounted gas generator on the ground and connect the heat exchanger 5 to the skid-mounted gas generator.

[0054] In this embodiment, step S2 further includes the method of inserting the heat exchange tube 6 into the mounting hole 24: S21: Fill the mounting hole 24 with bentonite 23. According to the actual situation, the bentonite 23 can also be tamped. Then rotate the outer tube 9 into the mounting hole 24 so that the spiral fins 11 are screwed into the inside of the bentonite 23 and enter the mounting hole 24.

[0055] S22: Insert the inner tube 10 into the inside of the outer tube 9.

[0056] S23: Tighten the connection cover 13 on the outer tube 9 and make the inner tube 10 extend out through the through hole of the connection cover 13. And tighten the connection nut 14 on the inner tube 10. It is also possible to first connect the connection cover 13 to the inner tube 10, then insert the inner tube 10 into the outer tube 9 and tighten the connection cover 13 on the outer tube 9.

[0057] S24: Connect the inner tube 10 to the outlet end of the delivery pump 4. Connect the connection nozzle 16 to the inlet end of the heat exchanger 5.

[0058] In this installation method, the principle of the outer tube 9 entering the bentonite 23 is the same as that of a screw being screwed in. It is convenient for the outer tube 9 to be inserted, and at the same time, after the outer tube 9 is screwed in, its surroundings are tightly wrapped by the bentonite 23, and the heat exchange effect is better. It is tighter than backfilling after the outer tube 9 is inserted.
